Academics Anne Allison, Thomas Schnellbächer, and Steve Ryfle have stated that Godzilla contains political and cultural undertones that can be attributed to what the Japanese had experienced in World War II and that Japanese audiences were able to connect emotionally to the monster. They theorized that these viewers saw Godzilla as a victim and felt that the creature's backstory reminded them of their experiences in World War II. These academics have also claimed that as the atomic bomb testing that woke Godzilla was carried out by the United States, the film in a way can be seen to blame the United States for the problems and struggles that Japan experienced after World War II had ended. They also felt that the movie could have served as a cultural coping method to help the people of Japan move on from the events of the war.[16][17][15]

Tim Martin from The Daily Telegraph (London) stated that the original 1954 film was "a far cry from its B-movie successors. It was a sober allegory of a film with ambitions as large as its thrice-normal budget, designed to shock and horrify an adult audience. Its roster of frightening images — cities in flames, overstuffed hospitals, irradiated children — would have been all too familiar to cinemagoers for whom memories of Hiroshima and Nagasaki were still less than a decade old, while its script posed deliberately inflammatory questions about the balance of postwar power and the development of nuclear energy." Martin also commented how the film's themes were omitted in the American version, stating, "Its thematic preoccupation with nuclear energy proved even less acceptable to the American distributors who, after buying the film, began an extensive reshoot and recut for Western markets."[20]

Japanese critics accused the film of exploiting the widespread devastation that the country had suffered in World War II,[75] as well as the Daigo Fukuryū Maru (Lucky Dragon) incident that occurred a few months before filming began.

He stated "The first film critics to appreciate Godzilla were those in the U.S. When Godzilla was released there as Godzilla, King of the Monsters! in 1956, the critics said such things as, 'For the start, this film frankly depicts the horrors of the Atomic Bomb.', and by these evaluations, the assessment began to impact critics in Japan and has changed their opinions over the years."[77]
